Washington’s wine map just gained a new name. The Columbia Hills AVA, officially recognized in August 2026, is Washington’s 22nd American Viticultural Area.
An AVA is a federally recognized grape-growing region with distinctive geographic or climatic features. Think of it as a wine’s home address, helping you understand where the grapes were grown.
COLUMBIA HILLS AVA AT A GLANCE
Located in Klickitat County in south-central Washington, Columbia Hills sits within the larger Columbia Valley AVA, between the Columbia Gorge and The Burn of Columbia Valley.
The AVA:
- Covers 29,387 acres
- Includes approximately 300 acres of wine grapes
- Follows a 35-mile ridgeline along the Columbia River
- Is led by Cabernet Sauvignon
Its south-facing slopes offer abundant sunlight, while the Columbia River helps moderate temperatures and extend the growing season. Shallow, well-drained soils bring vines closer to basalt bedrock, with sand, silt and gravel shaped by the ancient Missoula Floods.
What It Means for Woodinville
Many Woodinville wineries source grapes from regions across Washington, bringing the state’s wine map together in one tasting destination. As Columbia Hills begins appearing on wine labels, visitors may soon be able to discover Washington’s newest AVA right here in Woodinville.
